One-km Base Elevation (GLOBE) Project. The GLOBE Task Team was
established by the Committee on Earth Observation Satellites. It is part
of Focus I of the International Geosphere-Biosphere Programme - Data and
One-kilometer Base Elevation (GLOBE) Documentation. This is the
first version of documentation for the Global Land One-kilometer Base
Elevation (GLOBE) data set. GLOBE is an internationally designed,
developed, and independently peer-reviewed global digital elevation
model (DEM), at a latitude-longitude grid spacing of 30 arc-seconds
(30"). This report describes the history of the GLOBE project, the
candidate data sets, data compilation techniques, organization, and use
of the data base. The data are available on CD-ROM and the World Wide
